The invention relates to baling presses and has for its prime object theprovision of a baling press in which the 'platen is actuated by screwmechanism and is movable laterally Y, of the baling chamber beyond itsupper end 'J so that material may be inserted into the chamber throughits upper end. Vith this as well as other objects in view, the inventionresides in the novel features of construction and combinations andarrangements of parts as more fully hereinafter set forth.

In the drawings:

Figure 1 is a perspective view of a baling press embodying my invention;

Figure 2 is an end elevation thereof;

Figure 3 is a plan view thereof;

Figure 4 is an enlarged vertical cross section through a portion thereofshowing the manner of supporting the vertical screws.

1 is the base of the baling press, and 2 and 3 are respectively theframe and the baling chamber which are mounted upon the base. The framehas at opposite ends of the baling chamber the spaced vertical guidebars 4 connected by the cross bars 5 and secured at their lower ends tothe saddles 6 resting upon the base. 7 is the platen movable verticallywithin the baling chamber 3 and actuated from the vertical screws 8 and9 at the opposite ends of the baling chamber between the guide bars 4and the cross bars 5 and the ends of the baling chamber. These screwsare driven by suitable means such as the electric motor 10 which drivesthe drive shaft 11 eX- f tending longitudinally of the base 1 andprosisting the upward thrust of the screw which is caused by thedownward movement of the platen while compressing the material in thebaling chamber, I have provided the annular shoulder 16 upon each screwand located below the shoulder 15 of the saddle.

There is preferably the anti-friction bearing 17 between the shoulders16 and 15.

To permit of inserting the material into Vthe baling chamber 3 throughits open upper end, the platen is .connected to the screwsin such amanner that as itis raised out of and beyond the upper end of the balingchamber, it may be roclred laterally to clear the upper end, leaving thesame open, Specilically, the platen 7, is secured to the supporting bar18,

- which in turn is secured lat its ends to the connecting. rods 19`having hollow heads 2O at their upper ends forthe passage of the screwstherethrough. The lower ends of these connccting rods are pivotallyconnected to the A.

guide arms 23 upon the frame and engage-5 able with the supporting bar18 to force the platen laterally olf dead center, after which it willmove under the influence exerted by gravity as the nuts are raised untilit assumes a position at one side of the chamber.

connecting rods fulcrum intermediate their ends upon the frame as wellas slide about their fulcrum points until the platen has lmoved intoregistration with the upper end of the baling chamber, after whichfurther downward movement of the nuts lowers the platen.

Suitable anti-friction means such as the rollers 24 are preferablyprovided upon the versely thereof, rotatable screws at opposite;

.-, S0 Upon downward movement of the nuts, the

. ends of said chamber for raising and lower'- ing said platen,longitudinally spaced shoulders upon said screws, and means secured tosaid base and located between said shoulders t for limiting thelongitudinal movement of and screws in opposite directions, said meansincluding an anti-friction bearing.

2. In a baling press, the combinationwith a chamber having an open upperend, of a platen movable transversely of said chamber beyond said openend and also movable within said chamber, screws connected to saidplaten for actuating the same, and Vantiriction means cooperating withsaid screws for supporting saidV plateiiwhen in a transverse position ofadjustment.

3. In a baling press, the combination with a chamber having an openupper end, of a platen movable transversely of said chamber p beyondsaid open end and also movable within said chamber, and means foractuating said platen comprising screws and connecting rods between saidscrews and platen, and anti-friction means engageable with saidconnecting rods` when said platen is iii a transverse position ofadjustment. In testimony whereof I affix my signature.
